Lenox Tools - 3002828L LENOX Tools Bi-Metal Speed Slot Hole Saw with T3 Technology, 1-3/4

Ill leave it at that!

I use these in my tube notcher. I have used the same cutter to cut notches in schedule 40 pipe and 1 1/2 tubing and it just keeps going. No problems with broken teeth and it seems to stay sharp for a lot longer than I expected.

Building a set of speakers and needed to mount the tweeters. Seems I need and endless stream of new tools on this project. Oh well they will be useful later. Cut maple faced 3/4 inch plywood cleanly and fast. No issue over it not clearing the dust out of the cutting teeth. Didnt need to back it out once to clear it. Cant say that for another brand I bought.

Works well, Lasts long time.

I burned the teeth off this size in my Lenox hole saw kit, and this is the replacement. They modified the plug removal slots on the side so its even easier to clear the plug out. (I got a diamond hole saw for stucco in the future.)

ok

I have always had good luck with Lenox products and their hole saws in particular. However once mounted to arbor these are rarely very concentric and leave you with a rough hole that is often slightly larger than advertised aprox 1/16inch. If you want a perfect clean hole I suggest either carbide hole cutter or size yourself 1/16 smaller with these and finish with filing, grinding, sanding, ect.. Overall these are great quick way to make a hole in almost anything! Takes alot of abuse to ruin one of these even in steel. Remember to use compressed air to remove chips often a d alternate pressure bird pecking on metals.
